KM Task Scheduler

Question

dear all,
2 questions:
Q1
I created a scheduled task in the NWDS and deployed the par and configured the time table for it. The task is running every minute, so it's all working. Now i'm wondering, is it possible to set the user that executes the task somewhere? like in a service user or so.
When i call a bean method from the task,  and i call the myContext.getCallerPrincipal() in the bean, the calling user varies( sometimes Guest, sometimes my user id, ...)
Q2
I removed some tasks from the scheduler the way was described in the forum somewhere ( delete some .xml files in the src.config when creating the par and upload that par)
Now i reuploaded the par with the task xml's in it, and the task is created in my portal. When i assign a timetable and a cm system to it, i still get the "No CM systems assigned" message when i look in the component monitor and the startup of the task fails... Any idea why the portal doesnt recognize the updated task like it should?
Kind regards,
J.
